BOEM Seeks Comment on Gulf Oil and Gas Lease Sales
The Bureau of Ocean Energy Management (BOEM) will open a comment period and hold public meetings to prepare an environmental impact statement for proposed oil and gas Lease Sales 225 and 226 in the Gulf of Mexico, the agency announced in March.

This area includes 657,905 acres that are more than 120 miles offshore Alabama and Florida, not including the Straits of Florida, which is under a congressionally mandated leasing moratorium until June 2022.

The sales are part of BOEM’s proposed Outer Continental Shelf oil and gas leasing program for 2012 to 2017, which the bureau said would make more than 75 percent of the estimated undiscovered technically recoverable oil and gas there open to development.

Comments can be submitted to BOEM via email (boemegomeis@boem.gov) until May 4.


MTNW, Applied Measurements Retrofit Rowan Jack-Up Winches
Seattle, Washington-based Measurement Technology NW (MTNW) has installed and commissioned winch control systems for two Rowan Co. Inc. (Houston, Texas) jack-ups: the J.P. Bussell and the Gorilla II.

MTNW collaborated with Applied Measurements Inc. (Harlingen, Texas) on the retrofit of several Letourneau Technologies Inc.’s (Longview, Texas) W-1500 Anchor winches.

Before the J.P. Bussell, a 225-C Tarzan-class jack-up, and the Gorilla II, a 200-C Slotilever-class jack-up, commenced contract operations in southeast Asia last year, they underwent a controls and equipment retrofit at the Keppel FELS (Singapore) shipyard. MTNW was brought in during the retrofit by Applied Measurements to provide a programmable logic controller-based (PLC) monitoring solution for the mooring winch systems, which include running line tensiometers, a PLC control station with remote input/output, LCI-90i local displays and a central computer system combining existing monitoring software with new PLC interface functionality.

Applied Measurements chose to work with MTNW three-sheave line riders to monitor the jack-ups’ anchor winches. By integrating the line riders with the mooring controls, this system provided real-time feedback regarding the actions of the operator and the position/tension of the mooring line.

“We chose line riders because load pins are more accurate than hydraulic pressure or electric current in terms of winch monitoring,” said Graeme Cashen, Applied Measurements’ owner.


Caesar Tonga Project in Gulf Produces First Oil
The first production from the Caesar Tonga deepwater project in the Gulf of Mexico was established in March, operator Anadarko Petroleum (The Woodlands, Texas) and co-owners Shell Oil Co. (Houston, Texas) and Chevron (San Ramon, California) said.

Caesar Tonga is estimated to contain 200 to 400 million barrels of oil equivalent (BOE). Production from its first three wells is expected to reach 45,000 BOE per day. A fourth development well is expected to be drilled and completed later this year as part of the planned phase-one development.

Caesar Tonga, which included the first application of steel lazy wave riser technology in the Gulf of Mexico, is developed as a subsea tieback to Anadarko Petroleum’s Constitution spar floating production facility in about 5,000 feet of water in Green Canyon Block 680 as a host.


BP Cleared to Drill Deepwater Well Offshore Shetland Islands
BP plc (London, England) received approval in March to drill the deepwater North Uist well, northwest of the Shetland Islands, from the U.K. Department of Energy and Climate Change.

The North Uist well, in Block 213/25c, is 125 kilometers northwest of the Shetland Isles in a water depth of approximately 1,290 meters. The Department of Energy and Climate Change examined BP’s application, which included environmental impact and emergency response plans, and had no objections to the proposals.


Expro to Sell Connectors Branch To Siemens AG for $630 Million
Expro International Group (Reading, England) has agreed to sell its connectors and measurements (C&M) business, including the Tronic and Matre brands, to Siemens AG (Munich, Germany) for $630 million.

The transaction is conditional upon receipt of approval from competition authorities in Norway. Completion of the sale is expected in May 2012.

Expro’s C&M designs, manufactures, assembles and installs subsea electrical power and data connectors and temperature and pressure sensors. The C&M business had revenues of approximately $119 million in the calendar year 2011 and employs approximately 450 people.


Providence Strikes Oil Offshore Ireland in North Celtic Sea Basin
Providence Resources plc (Dublin, Ireland) discovered oil and gas in March in its Barryroe Well, located at 100 meters depth and kilometers offshore southern Ireland in the North Celtic Sea Basin. This is first large-scale commercial flow achieved offshore Ireland.

During well flow assessments, Barryroe produced flow rates of 3,154 barrels of oil per day, which exceeded Providence’s predrill target of 1,800 barrels of oil per day. A 24-foot-thick net pay interval was perforated as the first phase of the well testing program. Preliminary modeling of the pressure data indicates that a comingled flow rate of 3,350 barrels of oil per day at a flowing well head pressure of 500 pounds per square inch gauge is achievable. The well is 3 kilometers from pipeline infrastructure.

Providence said it plans to suspend the well for potential sidetrack drilling. All data obtained from these operations will be integrated with the 3D seismic data acquired in 2011. Providence, which has owned Barryroe since 2010, operates a standard exploration license on behalf of its partner Lansdowne Oil & Gas plc (Dublin).
